It is the object of this invention to provide a parachute attachment for aeroplanes which is so constructed and arranged as to automatically open when the aeroplane is accidentally tipped to an abnormal angle, and which will servetii right the aeroplane and prevent its falling at a dangerous speed in event of disability.

A further object is to provide a parachute attachment for aeroplanes which is simple in construction and eilicient and reliable in operation.

Other objects will appear hereinafter.

The invention primarily resides in an umbrella-shaped parachiito pivotally connected a short distance to one side of the center of gravity of an aeroplane, and" adapted to normally lie in a horizontal position, and means for automatically disten'ding the parachute when the aeroplane is dis osed at a predetermined angle, and inca'ns y which the opening of the parachute will operate to right the machine.

The invention further consists of the parts and the construction and combination of arts as hereinafter more fully described am? claimed, having reference to. the acconipanying'drawings, in which-- Figure 1 is a plan view showing the in vcntion as applied to an aeroplane. Fig. 2 is a "side eevation. of same showing the arachute in its normal horizontal position in full lines, and in the open position in dotted lines. Fig. 3 is a detail longitudinal section of the parachute, showing the mechanism for automatically 0 suing the same and illustrating in dotted ines the manner of opening the parachute and righting the aeroplane frame thereby.

In the drawin s A represents an acroplane which ma 6 of anysuitable type or construction. or the purpose of illustration let it be assumed that the center of avit of the aeroplane is situated at the The resent invention resides in pivotally mounting a frame 2 at one side of the center of gravity it, a short distance therefrom; in this case the frame. 2 being}; pivoted at 3 forward. of. the point-.01 gravity 3. The frame 2 is designed to normally extend in a horizontal direction and rest on gogrojection 5 on the side of the aeroplane y- Attached to the frame 53 is a rod 7, carrying a series of spmading ribs 8 on its outer end, to which are attached. lirucc ribs 9, connected to a sleeve 10, siidablc on the rod The spreading,- ribs 8 are covered with a suit able fabric 8' to form the pl'trnchute. "When the parachute is in its normal full position it will be disposed horizontally, as hown. in Figs. 2 and 3, with its oatmend A inkling into a circular plate or shield ll, liming: an annular flange 12 on its au'ror periphery, adapted to engage the outer ends of the ribs 8 of the parachute to retain the latter in its; folded position. The plate has a sliehl. reciprocal movement on tho. od 7, and, is normally held in i s iriLzei-umst position by means of a helical spa-11 13, wound on the rod '2 and bearing botnwn the rear of the plate 11 and a shhulder on the rod. 7. The shield 11 series to prevent air from entering' the parachute tending to open seine when the aeroplane is in motion.

Mounted oil-the rod 7 at a convenient point its acumen-n or frame 14, on which a lever 15 is pivotally mourned; one can ct tho lewr 15h slotteth'un ltl, and engages :1 pin 1'! on a sleeve 10', which noranally bears against the nl ceve 1 to which the bruceribs 9 are connected. The other end of the lever 15 is provided with a weight 18.

' In the operation oi the invention when the aeroplane 1 is accidentally tilted at an, abnormal angle, the weight 18 will operate to rock the lever 15 and move the sleeves 10 and 10 rearwardly on the rod 7, thereby causing the parachute ribs ti to spread: the ends of the ribs riding ovc r the inclined inner periphery of the flange 12 and thereby moving the plate 11 rcarwardly sufiiciently far to release the ends of the ribs 8 thercfrom. The moment the ribs pass beyond the (inter edge of the plate 11, air will be allowed to enter the parachute and thereby operate to open the latter in the usual man. As the ribs 8 are spread by reason of nor. the pressure of the air thereunder, the outer edge of the parachute is brought to bear upon the frame of the aeroplane at a point v on upwo (1 L point imwznrci otc' ch h I 3 and pull at the pofu oithe c r of gravity florwnwmi pressu'. e occasioned by mo the amchutc on oppoi-iitc sicio 2 cenier "cavity B, tench to restore iOIfiD': it normal position, in h position 5. mcrntainei by reason of to? of mvity 15 being rearward of t oi cos mension 3.
